Music is an art, entertainment, or other human activity that involves organized and audible sounds and silence. It is expressed in terms of pitch, rhythm, harmony, and timbre. Music involves complex generative forms in time through the construction of patterns and combinations of natural stimuli, principally sound. As a human activity, music may be used for artistic or aesthetic, communicative, entertainment, or ceremonial purposes. The definition of what constitutes music varies according to culture and social context.
The broadest definition of music is organized sound. There are observable patterns to what is broadly labeled music, and while there are understandable cultural variations, the properties of music are the properties of sound as perceived and processed by humans.A more conservative definition would be: Music is harmonious sound created by the playing of instruments as a whole or individually. It is a direct expression of human emotions designed to manipulate and transform the emotion of the listener/listeners. Music is designed to be felt unlike sound which is heard.
